Area Forecast Discussion
National Weather Service Spokane WA
203 AM PDT Tue Jul 23 2019

.SYNOPSIS...
Temperatures today will likely reach the 90s. There will
be an increasing risk for thunderstorms...especially tonight.
A cold front passage will moderate temperatures back to near normal
Wednesday, but will bring with it breezy winds. Dry and seasonably
warm conditions are expected for the end of the work week and through
next weekend.

&&

.DISCUSSION...
Today and tonight: An active period is in store tonight as a
strong negative tilt trough and cold front pass through the
region.

Today: Relatively quiet conditions are expected through the
afternoon as monsoon moisture coming up from the south tracks
mainly to our south and east across Central Idaho and SW Montana.
Models indicate quite a bit of instability over the Blue Mountains
into the Idaho Panhandle this afternoon but there should be
sufficient convective inhibition (50-100 J/KG) to prevent strong
surface based convection from forming. Could see a few elevated
storms develop late afternoon around the Blue Mountains, Camas
Prairie, and Central Panhandle Mountains. The main threat of
showers as well as potentially a few thunderstorms will be in the
Cascades with the approaching upper trough. Away from the Cascades
skies are expected to be mostly sunny with 850mb temperatures
warming to 23-26C yielding widespread highs in the 90s.

Tonight: Showers and thunderstorms will be on the increase this
evening as a slug of monsoonal moisture across Eastern Oregon gets
pulled north into Eastern WA/N Idaho. In addition large scale lift
will be increasing with the incoming trough. Elevated CAPE of
300-600 J/KG is progged from the past couple NAM model runs east
of a line from Hanford to Republic where the best threat of
thunderstorms is expected although isolated thunderstorms are also
possible in the Cascades and Okanogan/Methow Valleys. While the
storms will be quick moving tonight, the moist atmosphere and
strong atmospheric lift should promote locally moderate rain.
Models show the potential for a tenth to quarter inch of rain with
locally higher amounts across NE Washington valleys and mountains.
The fast moving nature of the storms across the Columbia Basin,
Spokane area, and Palouse should limit rain amounts to less than a
tenth of an inch for most locations where the Fire Weather Watch
will be upgraded to a Red Flag Warning where new fire starts from
lightning are possible. And with any new fire starts, winds are a
concern. 850mb winds increase to 25-35 kts with and behind the
front passage which combined with strong cold advection will
result in breezy to windy conditions. This may promote fire spread
for any grass/brush fuels that receive little to no rain. JW

Wednesday...By Wednesday morning the upper trough axis will be
hooking out of the area into Montana and Alberta. Some residual
showers and possibly leftover thunderstorms will impact the far
northeastern zones during the early morning hours but by afternoon
a sharply building follow-on short wave ridge will stabilize the
atmosphere for no further precipitation. The main issue on
Wednesday will be winds and dry conditions despite significantly
cooler temperatures. Strong cool advection in the wake of the cold
front invading the basin through the Cascade gaps will promote
solidly breezy and gusty conditions across the region. The
strongest wind potential will be in the morning and early
afternoon with locations near the Cascades with sustained winds
in the 20 mph range with gusts into the 30 to 40 mph range...with
a general 15 to 20 mph with gusts to 30 or so over the open range
of the eastern and central basin as well as south exposure higher
terrain north of the basin. Temperatures will be a good 10 to 15
degrees cooler on Wednesday than today...but dew points will
plunge into the 30s from the current 40s and lower 50s. This will
produce quite dry conditions and the the potential exists for
rapid fire spread in the range lands of the open basin despite the
cooler air mass.

Wednesday night through Monday...Models are in good agreement in
advertising a rather progressive flow regime over the region
through the remainder of the week and through next weekend
featuring flat short wave ridges or zonal flow punctuated by a few
weak short wave passages which will probably manifest themselves
as dry cold fronts...one currently expected on or about Friday
night and another possibly on or about Monday. This flow regime
will prevent any significant warm ups...with Friday just ahead of
the next short wave possibly the warmest day with high
temperatures popping a little above average before moderating back
to near average (generally the mid to upper 80s for this time of
year) with plenty of sunshine but breezy winds at time
particularly near the Cascade gaps. /Fugazzi

&&

.AVIATION...
06Z TAFS: A weak shortwave lifts in tonight, with limited shower
chances over SE WA/lower ID (PUW/LWS/COE) and even smaller risk
for t-storms tonight, with the threat of mainly sprinkles
elsewhere. A stronger system starts to move in late Tuesday,
increasing the threat of thunderstorms in the Cascades and
southeast WA/lower ID again in the afternoon, though the better
risk develops after 00Z near EAT, MWH near 03Z and near GEG-SFF-
COE-PUW-LWS between 03-06Z (and after). These will may be strong
with brief heavy rain, gusty winds and a threat of hail. Outside
of t-storms, however, primarily VFR conditions are expected.
